They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
Rusting of metal and tarnishing of silver are chemical changes because new substances are formed. Boiling water is a physical change as the water changes state from liquid to gas. Burning paper is a chemical change as the paper undergoes a combustion reaction to form new substances like ash and gases.
1 Burning of paper in the air. 2 Dissolving calcium in water 3 Slaking of Lime 4 Tanishing of silver when exposed to air 5 Clotting of blood in a wound.
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas

I don’t know the answer
Rusting and tarnishing are examples of corrosion because they involve the chemical reaction of a material with its environment, leading to degradation of the material's surface. In rusting, iron reacts with oxygen in the presence of water to form iron oxide (rust), while tarnishing involves the reaction of metals with substances in the air, such as sulfur or carbon dioxide, leading to discoloration and degradation of the material's surface.

rusting, burning, polymerizing,
Corrosion is the deterioration of a material, usually a metal, due to a chemical reaction with its environment. This can lead to rusting, tarnishing, or other forms of degradation.

Both are examples of oxidation.
Both processes require Oxygen. Rusting (I think) is where metal reacts with oxygen and moisture and becomes oxidises. Burning or combustion, ALWAYS needs Oxygen to occur. Hope this helps!
